SPECIFICATION forming part of Letters Patent No. 649,920, dated May 22,1900.

Application filed December 28,1897- Serial No. 664,118, (No model.)

To ail whom it may concern.-

Be it known that I, HARRY ELLIS, engineer, a subject of the Queen ofGreat Britain and Ireland, residing at 14L Leasowe avenueJVaL lasey, inthe county of Chester, En gland, have invented certain new and usefulImprovements in Looms for \Veavin g Leather and Like Belts, of which thefollowing is a specification.

This invention has reference to looms for weaving leather belts fordriving machinery and similar or other purposes, and has moreparticularly for its object to provide improvements by which the beltsproduced shall be firm and hard and tight woven and of equal strengthand elasticity throughout their width and also of such a character thatthere is no tendency or liability of any of the warps being undergreater tension or strain when the belt is in work than others, soobviating the breakage of individual warps.

In a loom according to this invention the leather warps or strings arewound on separate bobbins or reels, and each bobbin or reel has abraking device or retarding action by which a tension is put upon allthe warps and to the required degree during the weaving. The taking-offmeans, by which the warp and belt or fabric is drawn through anddelivered from the loom, consists of positively and intermittentlyactuated rollers, between which the belt or fabric passes and which areoperated from a part of the loom after each pick is completed. Betweenthe warp-bobbins and the heddles of the loom there is introduced aholding or gripping mechanism which holds all the warps during thebeating-up motion, so that a positive holding and tension of the warpswhile the beating up is be ing effected is obtained. During this timethe takingoff rollers are stationary, and then after this action thestopping or gripping mechanism is operated so as to release the warps,whereupon instantly the taking-0d rollers are actuated and the nextpicking moveinentis effected. According to one form of holding orgripping device there is an up per and under plate or jaw and one orboth of which are faced with india-rubbcr, and through these plates orjaws the warps are passed. By the use of the rubber face or faces thegripping of all the warps is assured,

as, although the warps will necessarily vary in size and thickness, yetwhen one plate or jaw is pressed onto the other by suitable means in thegripping action the rubber enables the jaws to be pressed sufficientlyclose so as to come in contact with and hold those warps which are thin,as well as those of course which are thicker. In one form of gripping orholding device there is one fixed jaw or plate and one moving part,which is moved up and down in any suitable Way by a suitable mechanism.The taking-off mechanism in one case consists of three rollersan upperand two lower rollersbetweeu which the belt passes when they areoperated, and this mechanism, the gripping or holding mechanism, and theheddles are all actuated from the same shaft of the loom, While the slayis operated by a separate mechanism.

In a loom for the weaving of leather belts or fabrics, as abovedescribed, the leather warps are wetted by drawing them through a bathof water in passing between the taking oif bobbins and the shed. Thisenables the weaving action to be performed with greater regularity andease and the packing of the warps to be better effected and generallyimproves the structure of the belt.

By the improvements above described in the first place the belt is wovenunder tension, as described, with the result that it is firm in texture;also, the tension of the fabric of the belt at different parts of itswidth is the same. Hence when the belt is in operation (it being assumedit is of a suitable design or stitch and nature of weaving) it is notliable to stretch at one side more than another or work crookedly orunevenly, and it is firm both diagonally and laterally; also, providedthe belt is of a suitable type of Weaving or stitch, it is thoroughlycompact and sound and in use does not stretch and become narrower orattenuated.

The loom above described is illustrated in the accompanying drawings, ofwhich- Figure 1 is a partial plan view. Fig. 1 is left-hand side ofFig. 1. vation.

d is the holding or gripping device,by which the warps are held.

e is the trough or bath containing water through which the warps arepassed, and f represents the reels or bobbins, each of whichcontains andhas wound upon it a separate leather warp, string, orthong.

1, 2, 3, and 4 designate the heddles, and g g are :the rollers above,from which the heddles are suspended, 1 and 2 being connected by bandsIt to the rolleng, and 3 and 4 being similarly connected to the roller gby the bands '71..

i 2' represent twosets of levers fulcrurned at i at either side of theloom and connected at their outer ends by cords i to the bottoms of theheddles, each heddle being connected at each side to one of the levers.The bed dles'are worked by these levers, and in action those connectedwith the heddles 1 and 3 will be up when those connected with heddles 2and- 4 are down,and vice versa. This arrangement of heddles is speciallyadapted for use in weaving leather belts of the type set forth in myspecification of application for patent v.. filed"D'e"cember 28, 1897,and serially numbered 664,117. The levers 11 are operated by suitablecams on the shaft i which is driven from the driving mechanism of theloom, as hereinafter described.

The completed belt shown in the drawings is designated 00, while thewarps from which it is partly made are denoted throughout the machine bythe letter 1 These warps, as stated, pass through the water in the bath6 from the reels f, passing under the rollers e, thence through a combor guide pin it on the upper side of the beam thence under the grippingand holding bar d, and then through the heddles and the slay. The completely=woven belt is passed through the takeoff rollers c, of whichthere are three, the taking off or feeding forward being effected bypassing it between the two back rollers, which, say, are stationary, andthe front roller, which is adapted to be moved up to and away from theback rollers by screws and hand-wheels c,which movethe bearings carryingthe journal of this roller, and thus by passing this roller on: to theothers, with the belt between them, the taking off is effected as therollers are rotated.

The taking-01f rollers, the heddles, and the gripping and holding bar (1are worked by one interconnected mechanism, while the slay is Worked bya separate or independent mechanism, and both of these mechanisms areadapted to be controlled and set in action and stopped by hand by theweaver from the end of the loom, and they are worked independently andat different times. The three first-mentioned parts or elements of theloom are operated through a belt-driven wheelj, which is mounted onshaft Z and is alternately made to revolve it and revolve upon itloosely without revolving it through a clutch-gear m of any knownsuitable kind, which revolves with the shaft and which alternatelyengages with and disengages from the wheel j, these actions beingperformed through the rod-and-lever connections 47%, operated by afoot-lever. The taking-off rollersare actuated from the shaft Z by acrank rt thereon, a connecting-rod 02 a pawl-lever and a pawl 71, andratchet-wheel n, engaged by the pawl, and spur-gearing 0, driven from apinion n on thespindle of which the pawl lever and ratchet-wheel n aremounted and fixed. By the rotation of the crank 01. it will be seen thepawl-lever n will be reciprocated, and the degree of each reciprocatingmove ment will determine the amount of feed or drawing-off movement ofthe belt after each beating-up action. g

The heddle-shaft 1 is revolved from the shaft l by the spur-wheels 1'and the warp gripping bar (2 is operated-that is, raised andlowered'from the shaft Z bya cam d on the shaft Z, a cam frame or ring dactuated by d, a lever (1 connected by a rod (1 with (Z and anadjustable rod 01 connecting the lever d with the gripping-bar through alever (1 which is connected to the center of the bar d by a link d Thusin action as the shaft Z revolves the cam (1 moves the rod (1 to andfro, and thereby lifts and depresses the gripping-bar d. Regarding themechanism for driving the slay, it is driven by a belt-pulleyp, whichdrives a shaft 19 and is alternately made to revolve this shaft orrevolve loosely upon it by a clutch q, similar to the clutch m, andoperated that is, thrown into and out of gear with the pulley--by therods and levers g, which are actuated by a hand-lever g at .the endof-the loom; The slay Z7 is rocked to and fro by this driving mechanismby a pinion r, meshing with a spur-wheel 4", which is fixed on anddrives a shaft 1*, extending through the loom laterally and having uponit at either end a disk 7*, these disks being 'connected with the slay bby connecting-rods 4. Thus as the shaft 13 is revolved the cranks rrotate and move the slay to and fro upon its hinges or pivots Z).

The loom shown is also provided with mechanisms for producing a beltmade'of warp and weft and stranded or corded selvages of the kind setforth in the specification of my concurrent application for patent filedDecember 28,1897, andseriallynum'bered 664,117. These mechanisms, whichare generally marked 3, consist of means of-laying up together strandsof leather thongs as thebelt is being made. As these mechanisms arefully described in my said other specification, their detailedconstruction and mode of operation will not be further described heremore than to say that they are rotated from the heddle-shaft from abeltpulley t, Fig. 1, thereon and belt through a belt-pulley t" on theshaft i and belt-pulleys s on the rotating tubular shaft of themechanisms" 5, the pulleys s being driven from the pulleys i Fig. 1, bybelts connecting them.

'It will be seen that the taking-oft rollers, heddles, and the warpgripping or holding means, and also the stranded or cordedselvage-making mechanisms when these are employed, are all driven by aset of interconnected mechanisms, as stated, and driven by a singlebelt, while the slay is driven by a separate mechanism and belt-drivinggear.

The operation of the loom and machinery is as follows: "When after theweft (which has been passed through the shed by the shuttle) has beenbeaten up by the slay the slaydriving clutch q is thrown out of gearwith the driving-wheel p and the clutch m is put into engagement withthe driving-pulleyj, the gripping-bar (Z and the mcchanis ms driven byit are set in motion. The part first operated being raised off thewarps, then the taking-off rollers receive partial rotation by theiractuating mechanism. The heddles are operated and make a fresh shed, andthe bar 01 is brought down onto the warps and presses them into thegroove or recess of the rubber face 70 Fig. 3, on the beam 70, and thusfirmly grips and holds them, the equal gripping and holding of all thewarps (which will be of different thickness) being effected by theyielding nature of the rubber strip k The clutch m is then thrown out ofgear with the wheel j, and all these parts and mechanisms described arebrought to rest. When this condition of things exists, the warps will beunder tension in the loom, the tension being effected by the warp-reelshaving a frictional device of any known suitable kind in connection withthem tending to prevent their rotation, and the shuttle is then putthrough The clutch q is then putinto gear the shed.

with the wheel 13, and the slay b is operated and drives the weft hardup against thecompleted fabric and then returns, whereupon the clutch qis thrown out of gear with wheel 1) by the hand-lever g and the clutch mis thrown into gear with the wheel j by the footlever m, and the cycleof operations is then repeated-that is, the gripping-bar d is raised offthe warps, the taking-01f rollers are rotated, and the heddles areoperated, as described.

In the term leather herein used it is intended that the Word shall beread to include both natural-zl a, animalleather and substitutes forleather or material which for the present purpose of its applicationwould be practically analogous or equivalent to it.

What is claimed in respect of the herein described invention is 1. In aloom for making woven-leather belts, the combination of a slay, theheddles, taking-cit rollers and means for gripping and holding the warp,a driving mechanism connected with the heddles, take-oft rollers andwarp-holding means and a separate driving mechanism for operating theslay, substam tially as described,

2. In a loom for making woven leather belting, the combination of thetaking-off means, the heddle mechanism and warp-holding mechanismarranged to be at rest while the beating-up motion is operating and withthe warp-holding mechanism gripping the warp, driving mechanism for saidparts including stopping and starting means, abeating-up motion and adriving mechanism for the same, independent of that first mentioned withstopping and starting means, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

HARRY ELLIS.
